Format

"Old format" files have a 6-byte header, and "modern format" files have an 8-byte header.

Identifiers

The MGR software does not appear to use any filename extension for this format, but some third-party software uses .mgr.

Identification

Files begin with a two-byte ASCII signature:

Signature Format
"yz" modern format, 8-bit aligned
"yx" modern format, squeezed
"xz" old format, 1-bit, 32-bit aligned
"zz" old format, 1-bit, 16-bit aligned
"zy" old format, 8-bit, 16-bit aligned
